How should we select winning bids of generation units for strategic reserves that consist of capacity bids and energy bids? In this paper, we analyze two selecting mechanisms (scoring rules): "simultaneous" and "sequential". In case of a simultaneous scoring rule, capacity and energy bids are...

This paper proposes a simple model for multiple second-price auctions which run parallel to each other, in the sense that though they might not begin or end at the same time, they have certain periods of overlap. We characterize the equilibrium bidding strategy of the buyers and the equilibrium...

This paper models sequential auctioning of two perfect substitutes by a strategic seller, who learns about demand from the first-auction price. The seller holds the second auction only when the remaining demand is strong enough to cover her opportunity cost. Bidding in anticipation of such a...

An auctioneer faces a pool of potential bidders that changes over time. She can delay the auction at a cost, in the hopes of having a thicker market later on. We identify a property of the distribution of bidder values—its “price elasticity”—that governs the distortions caused by revenue...

This paper extends the results in Hidvegi et al. (2006) to the case when the number of bidders is common knowledge in an English auction with buy-out. In that case when some bidders drop out, the remaining bidders have to update their information, and change the threshold auction price at which...

Motivated by challenges facing IT procurement, this paper studies a hybrid procurement model where a reverse auction of a fixed-price IT outsourcing contract may be followed by renegotiation to extend the contract's scope. In this model, the buyer balances the need to incentivize...

We study all-pay auctions with budget-constrained bidders who have access to fair insurance before bidding simultaneously over a prize. We characterize a unique equilibrium for the special cases of two bidders and one prize, show existence and a heuristic for finding an equilibrium in the case...
